2 Claims.

My invention pertains to stock enclosures that are electrically chargedand more particularly to single or multiple electrically charged wiresmounted on supports, encircling a field or yard, thereby forming anenclosure.

The object of my invention is to provide an enclosure that has theelectricity controlled in such a manner that it will not prove fatal tothe animal contacting it.

Other and further objects of my invention will become readily apparentto persons skilled in the art from a consideration of the followingdescrip tion when taken in conjunction with the drawing, wherein Fig. 1illustrates the enclosure in perspective, with the electrical controlunit mounted on one ci the posts or supports.

Figure 2 illustrates the method Aemployed to vary the current byshorting a resistor.

Similar characters of reference indicate corresponding parts throughoutthe several views, and referring now to the same, character I0,indicates the current supply lines to the unit. Choke coils are shown bythe character II, and the character I2 indicates condensers. The primarywindings ci the transformer are indicated by a numeral i3, while thesecondary windings or coils oi 'the transformer are shown as I4, on thedrawing. The character I 5, applies to the ground Wire. There is acircuit closing device, on which the contact points are shown as I6, andthe metal strip on the circuit closer is indicated as Il. There is aheating element I8, which acts on the metallic strip l? of the circuitcloser, causing same to expand and contract periodically. The character2U, shows a resistor to allow the current to pass when the points areopen in the circuit closer, While character 2|, indicates the contactarm. Character 22, illustrates a spring to actuate the contact arm.Character 23, indicates contact pointsy while 24, designates a resistorto pass the current when contact points are opened. Lamps in thecircuits are shown as 25. These lamps flash periodically to act as asignal and/or prevent dead shorting of source of supply. Condensers areshown as 27, and the electro-magnets as 28, in the drawing. The actualfence wire is indicated by the numeral 32.

In operation the unit controls the electricity reaching the fence wirein the following manner. Parts II, IIA and I2 constitute an interferencefilter, while the parts I6, I'I and I8,.compose a conventional type ofcircuit closer which opens and closes periodically due to the expansionand contraction of the strip I1, acted upon by the heating element I8.The current flows through choke coil il, and the primary winding I3, ofthe transformer, back to the supply line I0, through the choke coil IIA.While the current flows through the primary winding I3, it induces acur- 5 rent in the secondary winding I4, of the transformer, whichcharges the fence.

The illustration in Fig. 2 shows a circuit closer composed oi parts IS,I'l and I8, to vary the current periodically through the primary windingl0 I3, of the transformer. This is accomplished by snorting the resistor20, and varying current is thus induced in the secondary winding I4. ltis again varied by the combination of parts 2|, 22, 23, 25, 2'! and 28,before imparted to the enclosure 15 wire 32. The device for varying thesecondary current functions on the principle of a buzzer, but contactpoints 23, are held open longer due td energy absorbed by the condenser2l. The snorting of the resistor 24, by the points 23, varies 29 thecurrent. This electro-magnetic current varying devicel completes thecycle comparatively faster than the circuit closer in the primarycircuit and the ultimate result is a varied current imparted to the wireforming the enclosure. The lamp 25, acts as a signal device.

l' have entered into a detailed description of the construction andrelative arrangement of parts embraced in the preferred embodiments ofmy invention in order to impart a full, clear, and ex- 30 actunderstanding of the said embodiments. I do not desire, however, to beunderstood as confining myself to the said specific construction andrelative arrangement of parts inasmuch as in the future practice of theinvention, various changes and modifications may be made such as fallwithin the scope of the invention as dened by my appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent in 'the United States, is:

l. A stock enclosure of the character described, comprising an electriccurrent supply, a contact means for engagement by stock confined in theenclosure, a transformer having a primary winding and a secondarywinding, a resistor in series with the said primary Winding, a circuitmaking and breaking device connected across said resistor for 4varyingthe current in the said primary winding, and an electro-magneticallyoperated vibra.- tor in series with the said secondary winding forcharging the enclosure contact means.

2. A stock enclosure of the character described, comprising the leadsfrom an electric current supply, a contact means for engagement by stockconfined lin the enclosure, a lter circuit including a choke coil ineach of the said supply leads, condensersconnected across said supplyleads, said condensers -being grounded, a transformer having a primarywinding and a secondary winding, a. resistor in series with the saidprimary winding, a periodically operating circuit closer connectedacross said resistor for varying current in the circuit of the saidprimary winding, and an electro-magnetically operated vibrator in serieswith the said secondary Winding,1 for chargingvthe enclosed contactmeans.
